- Usage patterns derived from RECS (Residential Energy Consumption Survey), EIA's official survey of US household energy use.
- Carbon footprint calculated using EPA eGRID emissions factors specific to your regional grid mix in North Carolina.
Authoritative US energy data sources:
- EIA Electric Power Monthly — official US electricity rate data by state
